Jehovah a great king over all the earth

Psalm 47 only pursues this deliverance to its bright results for
Israel according to God's glory in the earth. Jehovah is now a
great King over all the earth (compare Zech. 14). He subdues the
nations under Israel and Himself chooses their inheritance. This
is triumphantly celebrated from verses 5-9, and the association of
the princes of the peoples now owning God, with the people of the
God of Abraham. He is specially Israel's (the remnant's) King, but
if He is, He is King of all the earth. In these verses God Himself
is celebrated, but He is the God of Israel. It is the celebration
of the earthly part of the millennial glory of God: Israel owned
in the delivered remnant being the centre. I apprehend verse 9
should be "have joined themselves to the people."
